We’re publishing this as an emergency bulletin for our customers and the larger web community. A few hours ago a zero day vulnerability emerged in the Tor browser bundle and the Firefox web browser. Currently, it exploits Windows systems with a high success rate and affects Firefox versions 41 to 50 and the current version of the Tor Browser Bundle which contains Firefox 45 ESR.
We are urging our customers to follow the protocols provided in this Emergency Bulletin and cease use of Firefox until a patch has been released. Feel free to contact us with any questions or concerns that you may have regarding this announcement.
